Abstract
Under the existence of shielding, the images observed by two eyes are positioned in un-corresponding regions (single-eye regions); in the popular three-dimensional vision theory, the single-eye region is used as noise abandoning; and a two-eye three-dimensional image synthesized in certain occasions according to the theory is severely inconsistent with natural objects seen by the two eyes, so that the three-dimensional effect is influenced. The invention discloses a method for three-dimensionally synthesizing the images observed by the two eyes under existence of shielding. The single-eye region is retained under the action of compression and displacement of a shielding region, so that the three-dimensionally synthesized image is consistent with the natural objects seen by the two eyes.
Description
Technical field:
(taking the photograph) picture that field of the present invention relates to take, stereoscopic vision, aerial survey, monitoring, traffic administration, criminal investigation, fields such as stereo microscope.
Background technology:
Block almost ubiquitous in daily life: bus has blocked private car on the road of traffic congestion, and truck has blocked public transport, and people's police have blocked truck, and the onlooker has blocked people's police again; In the open air: the house has blocked trees, and trees have been blocked mountain, and they have blocked sky together; Indoor: tables and chairs, stool, desk lamp, door blocks mutually again.Because block, watch that at a distance of 6-7 centimetre of people's two the shelter rear backdrop is different, shelter is when preceding, and right eye is seen shelter, and the right is partly many behind, and left eye sees that left-hand component is many.These parts that can only simple eyely see are called simple eye district in document.
In popular stereoscopic vision (Hui Sideng stereoscopic vision) theory, because this part zone can not find corresponding point, there is not parallax, be taken as noise and abandon.But in a large number confirm that about the researchs in simple eye district simple eye district played vital role in the formation of depth perception and stereoscopic vision over nearly 30 years, in stereoscopic vision research, can not ignore.The stereoscopic vision of the considering simple eye district Leonardo da Vinci's stereoscopic vision that is otherwise known as, present domestic researcher is considerably less.
In fact in daily slr camera is taken, that scenery that the cameraman finds in view-finder, to see for a long time and actual eyes are seen and inconsistent.Promptly use stereoscopic camera to take, if watch without special devices (prism, double-colored eyeglass etc.), image that is synthesized and normal eyes finding and inconsistent.Under the nature situation eyes in addition can see shelter fully after background, but under such stereoscopic vision theoretical direction, can't see eyes easy fatigue again when using specific installation to watch in the synthetic stereoscopic image.The synthetic application for a patent for invention of disclosed relevant stereoscopic image on the State Intellectual Property Office website. for example; Number of patent application is that 201010253597.2 applications for a patent for invention " synthetic method of stereoscopic image " and number of patent application are that 201010257568.3 applications for a patent for invention " a kind of method of representing the picture and text stereoscopic visual effect " are exactly to belong to the stereographic middle stereographic system of cylindrical lens (grating).The flickering of the image that forms like this is difficult to avoid fully, therefore lacks the quantitative measurement orientation effect that can supply scientific research to use, and can't be used for stereomicroscope, aviation, and geodetic surveying etc. is located.
Therefore can be according to the mechanism of human stereoscopic vision; Invent a kind of method of new synthetic stereo-images; Need not cut apart binocular images, it is synthetic by the eyes viewing system again to deliver to eyes, observes timeliness fruit (haplopia and directly just can obtain nature from composograph; Prospect is outstanding, can see more background) demand arranged.

Summary of the invention:
The technical matters that the present invention will solve provides the three-dimensional synthetic method of a kind of binocular images based on human binocular vision mechanism.
Technical solution of the present invention is that the method that provides a kind of image to synthesize, described synthetic method are based on the compression of the common blocked area of binocular images under the computer software and move and realize, may further comprise the steps:
(1) imports the original binocular stereoscopic figure that takes with stereoscopic camera to (taking same field of view simultaneously obtains);
(2) binocular images with gained is simultaneously displayed on the screen, and both are overlapping, lets common ground overlaps basically among the figure.
Order:
S
k(i，j)＝f
l(i，j+k)-f
r(i，j)
(wherein subscript L representes left eye to fl in the formula, and subscript is changed to the digital image that R is a right eye for i, the capable j row of i pixel value during j) expression left side eye pattern resembles, and this moment, K was between two width of cloth images, the horizontal direction alternate position spike.
The value of regulating K makes Min S (k), when S (k) hour two figure accomplish and merge, this moments two figure center section basically identicals, common region is that k is between m-k.
(3) under central shelter situation, the true origin of the coincidence of binocular images is placed on blinkpunkt, normal condition be exactly binocular images will be that fulcrum overlaps adjusting with the blinkpunkt.Two figure are basic after accomplishing initial adjustment overlaps, but on the both sides, blocked area, owing to block, it is minimum that the binocular images signal difference can't reach.
(4) according to the research of psychology Physical Experiment, human viewing system is through the compression to the shelter zone, and the synthetic of this part zone accomplished in displacement.It is synthetic that the present invention is that the such method of design is accomplished the solid of binocular images at present: at this moment we can be divided into 3 parts to the image of eyes; Two parts of seeing jointly are a district near the blinkpunkt; L representes with subscript, and two other not counterparts in common district are called 2 districts, and remaining part is 3 districts.Indexing is distinguished the Left or right of the blocked area that is which eye; At first viewing system is separately checked toward both sides from blinkpunkt that two width of cloth picture registration situation exist together to be retained mutually and is come; Two blocked area is identical just being preserved in principle, has arrived the background place owing to block right and left eyes finding difference, at first regulates the blocked area compression that making eyes common through Computerized image processing system; The right-hand component regulation that is available; The respective signal that eye image is come is constant, but suppresses the signal that this regional left eye comes, and the signal that makes this district deliver in the consciousness is the f that the right eye comes
b(I, j)=α
rf
r(I, j)+α
lf
l(I, j)=α
rf
r(I, j) (α
l=0; I, j ∈ Ω nr); The respective signal that the left eye nethike embrane comes in the left-hand component that in like manner is available is constant, but suppresses the signal that this regional right eye comes, and the signal that makes this district deliver in the consciousness is the f that left side eye comes
b(I, j)=α
rf
r(I, j)+α
lf
l(I, j)=α
lf
l(I, j) (α
r=0; I, j ∈ Ω nl), when the such adjusting repeatedly of process; Other parts of eyes overlap basically, and then the new images of gained has not only comprised two common blocked areas, also comprise two because of stopping up the simple eye district that forms; The composograph that obtains will be consistent in observe same view naturally with eyes.
(5) when shelter during on both sides, compress common occlusion area, the position that is available is filled by following rule by the simple eye district of adjacent area part: shelter the right eye image partly remains unchanged, and is filled in the right-hand component that compression is available; The right left-eye image part zero clearing, overlapping only keeps the independent finding of right eye, and compression process proceeds to remaining zone, and both are consistent; Partly remain unchanged with method shelter left side left-eye image, be filled in the left-hand component that compression is available; Left side eye image part zero clearing, overlapping only keeps the independent finding of right eye, and compression process proceeds to remaining zone, and both are consistent.Composograph will be with to observe same view naturally with eyes consistent.
